Fig.A

This is one of our MX series brackets, which allows the visible front portion of the bracket to be easily removed from

the front of the vehicle (Fig.A and Fig.B). The bracket kit consists of a passenger and driver side main receiver brace, two removable front braces and a hardware pack. The main re-ceiver braces mount to the frame, cross mem-ber, lower frame rail and to the bumper core; the removable front braces install in the main receiver braces.Before starting the installation, lay out the kit components in order, as they will be used. This will give you a visual idea of how the compo-nents work, and will also confirm that every-thing is present and accounted for.

IMPORTANT: All brackets must be assembled with all the bolts left loose for final adjustment and positioning (before tightening) unless otherwise instructed. All bolts must be torqued for proper strength. If more than one bolt is used per fastening point, the diagram may only show one.

• Use flat washers over all slotted holes • Use lock washers on all fasteners

• Installation of most mounting brackets requires moderate mechani-cal aptitude and skills. We strongly recommend professional installa-tion by an experienced installer.

• The installer must read the instructions and use all bolts and partssupplied. Failure to do so could result in loss of the towed vehicle.

• Use Loctite® Red on all bolts used for mounting this bracket.

• Every 3,000 miles, the owner must inspect the fasteners for propertorque, according to the bolt torque requirements chart on the last pageof these instructions. The owner must also inspect all mounts andbrackets for cracks or other signs of fatigue every 3,000 miles.Failure to do so could result in loss of the towed vehicle.

• The owner must check the vehicle manufacturer's instructions forthe proper procedure(s) to prepare the vehicle for towing. Somevehicles must be equipped with a transmission lube pump, an axle dis-connect, driveline disconnect or free-wheeling hubs before they can betowed. Failure to properly equip the vehicle will cause severe damageto the transmission.

• If running changes were made by the vehicle manufacturer after thisbracket was designed, some bolts or other fasteners in the hardwarepack may no longer be the correct size. It is the installer’s responsi-bility to verify that the bracket is securely fastened to the vehicle andfitted with the correct hardware to account for these changes. Failure tosecurely fasten the bracket could result in loss of the towed vehicle.

• If the towed vehicle has been in an accident, it must be properly re-paired before attaching the bracket. Do not install the bracket if anystructural frame damage is found. Failure to repair the damage couldresult in the loss of the towed vehicle.

• Roadmaster manufactures many styles of brackets. If your brackethas removable arms, they must be removed before driving thevehicle, unless the arms can be pinned or padlocked in place.If not secured, the arms could vibrate out, resulting in non-warrantydamage or personal injury.

• Some motorhome chassis have such a tight turning radius that you candamage your motorhome, towed vehicle, tow bar or bracket while turningsharply. Before getting on the road, test your turning radius in anempty parking lot. Turning too sharply could result in non-warrantydamage to towing system, motorhome and/or towed vehicle.

• Do not back up with the towed vehicle attached or non-warrantydamage will occur to your towing system, motorhome and/or towedvehicle.

• The safety cables must connect the towing vehicle to the towedvehicle frame to frame, with the cables crossed, with enough slackfor sharp turns. Refer to the cable instructions for proper routing.Failure to leave enough slack in the safety cables, or failure to connectthe safety cables frame to frame, will result in the loss of the towedvehicle.

• This bracket is designed for use with ROADMASTER tow bars andROADMASTER adaptors only. Using this bracket with other brands,without an approved ROADMASTER adaptor, may result in non-warranty damage or injury.

• Do not use this document for custom fabrication, as it may not showall parts or structural components. Custom fabrication or an attempt tocopy this bracket design could result in loss of the towed vehicle.

• Upon final installation, the installer must inspect the bracket to en-sure adequate clearance, particularly around hoses, air conditionerlines, radiators, etc., or non-warranty damage to the towed vehiclewill result.

• This bracket is only warranteed for the original installation. Installinga used bracket on another vehicle is not recommended and will voidthe warranty.

Failure to follow these instructions can result in property damage, personal injury or even death.WARNING

1. Important: please use all supplied bolts and parts and read all instructions carefully before beginning thisinstallation. The majority of questions you may have can be answered within the text, and proper installation will ensure safe and secure travel. Now, begin the installation. Start by removing six plastic fasteners to remove the rock guard. Four of the fasteners are located in the front of the rock guard (Fig.C), and two are located in the back.

2. Remove four 18mm (head) nuts from each side. Two are on the inside of the frame rail (Fig.D) and two are on the out-side of the frame rail (Fig.E). Now, pull forward on the bumper core and unplug the fog lights, if the vehicle is so equipped. Remove the four plastic fasteners attaching the wiring harness to the back of the bumper core. Remove the bumper core (Fig.F) and set it aside.

3. Working on the driver's side, place the main receiver brace over the end of the frame rail (Fig.G).

4. Using the two supplied ½" x 1¼" bolts, bolt through the outside of the main receiver brace and through the frame rail.Place a ½" flat washer on the inside edge of the frame rail and finish with a lock washer and nut (Fig.H).

Note: on some early models, there are different bolt patterns in the lower frame rails. For these models, die grind the center and bottom holes in the frame slightly on both sides down and toward the front of the vehicle. Figure I (passenger side) shows the holes enlarged. Due to frame variances, the inside upper hole may need to be enlarged or redrilled.
